simple cyst can be quite normal and often disappear on their own. if they grow to 5 cms or more your doc may decide to remove it. 99% of all cysts are benign so try not to worry. It is normal practice to have another ultrasound a month or so later to check if it has gone or grown in size so although the waiting is not nice you seem to be getting good care.all the best, sharon
i don't know much about cysts, but the prominent endometrial stripe could be due to taking tamoxifan for the past two years. also, not seeing the other ovary isn't a concern, either. it's not unusual to not be able to see an ovary past menopause. as for the cyst, there are several women on this site who are very knowledgeable about cysts and they can probably give you some information. good luck :)
